i. Channel conflicts are detected based on the Permissive programming
jumpers on the Program Card for each channel. This operation
remains unchanged from normal Nema operation.
b.
Red Fail
i. A Red Fail fault will occur if the solid Red Arrow AND solid Yellow
Arrow AND flashing Yellow Arrow AND solid Green Arrow all remain
inactive for the Red Fail fault response time. The fault icon (
) will be
displayed for both channels of the pair. The Red and Yellow inputs for
channels 1, 3, 5, 7 do not affect the Red Fail condition for the FYA
channels 13, 14, 15, 16 [9, 10, 11, 12].
c.
Dual Indication
i. A Dual Indication fault will occur if any two or more of the solid Red
Arrow, solid Yellow Arrow, flashing Yellow Arrow, or solid Green Arrow
signal combinations are active simultaneously for the Dual Indication
fault response time. The fault icon (
) will be displayed for the FYA
channel 13, 14, 15, 16 [9, 10, 11, 12]. The fault icon (
) will also be
displayed for the solid Green Arrow channel (1, 3, 5, 7) IF the solid
Green Arrow was active.
ii. If the RG, RY, or GY Dual Indication function is enabled for the solid
Green Arrow channels (1, 3, 5, 7) then a Dual Indication fault will occur
if any two or more of the Red, Yellow, or solid Green Arrow inputs (1,
3, 5, 7) are active simultaneously for the Dual Indication fault response
time.
d.
Clearance
i. A Clearance fault will be detected if the channel pair sequences from
the solid Green Arrow (1, 3, 5, 7) to the solid Red Arrow (13, 14, 15, 16
[9, 10, 11, 12]) without a minimum clearance time on the solid Yellow
Arrow (13, 14, 15, 16 [9, 10, 11, 12]). The fault icon (
) will be
displayed for the FYA channel (13, 14, 15, 16 [9, 10, 11, 12]).
ii. A Clearance fault will be detected if the FYA channel sequences from
the flashing Yellow Arrow (13, 14, 15, 16 [9, 10, 11, 12]) to the solid
Red Arrow (13, 14, 15, 16 [9, 10, 11, 12]) without a minimum clearance
time on the solid Yellow Arrow (13, 14, 15, 16 [9, 10, 11, 12]). The fault
icon (
) will be displayed for the FYA channel (13, 14, 15, 16 [9, 10,
11, 12]).
iii. A Clearance fault will be detected if the Green Arrow (1, 3, 5, 7)
channel sequences from the solid Green Arrow (1, 3, 5, 7) to the solid
Red Arrow (1, 3, 5, 7) without a minimum clearance time on the solid
Yellow Arrow (1, 3, 5, 7). The fault icon (
) will be displayed for the
solid Green Arrow channel (1, 3, 5, 7).
3.11.2 COMPACT FYAC MODE
3.11.2.1 FYAC TYPE 16 MODE
The Compact FYAc mode requires that the protected Green arrow signals be driven by the
unused Ped Yellow load switch outputs on channels 9, 10, 11, and 12.
In the Type 16
mode, the MMU-16LE SmartMonitor
®
will automatically remap the channel 9, 10, 11,
and 12 Yellow physical inputs to logical channel 13, 14, 15, and 16 Green status.
The
associated solid Red Arrow, solid Yellow Arrow, and flashing Yellow Arrow (FYA Overlap
phase) must be driven by a load switch monitored on channels 1, 3, 5, and 7 respectively.
The MMU-16LE
SmartMonitor
®
associates channel 1 with 13, channel 3 with 14, channel 5
with 15, and channel 7 with 16 when FYA monitoring is enabled for that respective
approach.
Note: Using the Compact FYAc mode allows a standard twelve position load bay to provide
the necessary signals without the addition of load switches for the FYA approaches. The
automatic remapping of the channel 9, 10, 11, and 12 Yellow inputs by the MMU-16LE
SmartMonitor
®
then eliminates the need to modify cabinet wiring. This mode requires that
